TRITON3 Phase 3 Trial of Rubraca® (rucaparib) Achieves Primary Endpoint in Men with Metastatic Castration-Resistant Prostate Cancer with BRCA or ATM Mutations
Clovis Oncology, Inc. (NASDAQ: CLVS) today announced positive top-line data from the Phase 3, open-label, multicenter, randomized TRITON3 trial demonstrating that Rubraca monotherapy treatment achieved the primary endpoint of significantly improved radiographic progression-free survival (rPFS) by independent radiology review (IRR) compared with the control group, which consisted of physician’s choice of docetaxel, abiraterone acetate, or enzalutamide
BOULDER, Colo.--(BUSINESS WIRE)--Oct 3, 2022--
Clovis Oncology, Inc. (NASDAQ: CLVS) today announced positive top-line data from the Phase 3, open-label, multicenter, randomized TRITON3 trial demonstrating that Rubraca monotherapy treatment achieved the primary endpoint of significantly improved radiographic progression-free survival (rPFS) by independent radiology review (IRR) compared with the control group, which consisted of physician’s choice of docetaxel, abiraterone acetate, or enzalutamide. Benefit was observed in both primary efficacy analyses of patients with chemotherapy-naïve metastatic castration-resistant prostate cancer (mCRPC): first, those who had mutations in BRCA, as well as all patients randomized in the trial, inclusive of mutations in BRCA or ATM (the overall intent-to-treat population (ITT)). The safety profile of Rubraca observed in the TRITON3 study was consistent with Rubraca labelling.
During the first quarter of 2023, the Company plans to submit a supplemental New Drug Application (sNDA) to the FDA for the BRCA subgroup of patients and intends to discuss with the FDA submitting for the broader ITT population.
“We believe that the positive results from TRITON3 further demonstrate the important role that Rubraca can play as a treatment option for men with metastatic castration-resistant prostate cancer associated with homologous recombination deficiency, and we look forward to submitting these data to the regulatory authorities in the US during Q1 2023. Not only does this provide a potential treatment option for eligible men with earlier stage disease, but it is the first and only PARP inhibitor that has demonstrated superior radiographic PFS compared to chemotherapy, which is today the standard of care for these patients,” said Patrick J. Mahaffy, President and CEO of Clovis Oncology. “Most importantly, I would like to thank the patients, physicians, and our colleagues whose commitment to this trial made these results possible, which now offer the potential to make a difference in the lives of many men with advanced prostate cancer.”
